Recently I have seen an increase in customers requesting the ability to identify the original payment used for a web order, to complete an automatic refund from store (POS) to that same payment. For example, if I use my PayPal account on the website. when I return the goods to a store, the store just refunds straight to my PayPal account. Obviously an override is needed in case the customer requests differently (maybe that paypall account has been closed). I also know this depends on the payment connector / provider abilities, but the key is a button in POS to refund to the web payment method used, and then for the payment connector to attempt it and authorise it LIVE. Hope that makes sense. Feel free to reach out it not!
